In the beginning of Chapter 4, Nick lists all of the people that were in attendance at Gatsby’s party. It’s interesting to think about why he does this. First of all, it shows that he is observant of exact details and it also shows that he has a good memory of each Gatsby party he attends. It’s ironic when he talks about a man he says “...whom we called Duke, and whose name, if I ever knew it, I have forgotten.” He finds it important that he doesn’t remember one man’s name, but he recalls every other person at the party which is pretty impressive. Later in the chapter Nick gets more acquainted with Gatsby. The pair go out for lunch and Nick learns a little more about Gatsby’s past. He finds that parts of the rumors are true like the fact that he served in the military and was an Oxford man. He also learns more about Gatsby’s friends when Nick is introduced to Meyer Wolfshiem. The biggest secret he discovers is that Gatsby wants a favor from Nick: for him to have him over for tea with Daisy, the girl he loves. Daisy and Gatsby were once a couple, but split up because of the war. Fearing that Gatsby would never return, she married Tom (with regret) only for him to return from war and move across the bay from her. The sole reason why Daisy moved on to Tom was because she needed comfort for the loss of Gatsby, who may or may not have been dead. She needed somebody to be with to make her feel special. This is why she remained faithful to Tom even though he cheats on her. Gatsby, however, never moved on. He purposely bought the house across from her to watch her and hope she came to one of his parties. Maybe that’s the reason why he had the parties? To hope she would come among the hundreds that did.
